Backspace deletes everything I just added?

Using Chrome, when NOT in a task/cell, when you hit backspace I think the browser takes thinks I want to go back to the "previous page", which then reloads all GQueues, and nothing (apparently) is saved.... so I lost all the bajillion tasks I had just entered in the past 15 minutes. Is there a way to fix that?
